SUMMARY:VIRTUAL INPA SEMINAR – Micah Buuck (SLAC)
DESCRIPTION:Speaker: Micah Buuck (SLAC) \nTitle: Neurtrinoless Double-Beta Decay and Radioactive Backgrounds in the MAJORANA DEMONSTRATOR \nAbstract: Neutrinoless double-beta decay (0νββ) is a lepton-number-violating process whose existence would indicate that neutrinos are Majorana fermions. The MAJORANA collaboration is searching for 0νββ in germanium-76 using a modular array of high-purity germanium detectors\, housed at the Sanford Underground Research Facility in Lead\, South Dakota. This presentation will show the results of an in-depth study of the backgrounds visible to the array\, and the details behind a model to explain their sources. \nJoin Zoom Meeting \nhttps://lbnl.zoom.us/j/99678795337 \nMeeting ID: 996 7879 5337

SUMMARY:VIRTUAL INPA SEMINAR – Jorge Morales (SLAC)
DESCRIPTION:Speaker: Jorge Morales (SLAC) \nTitle: Simulation of Dark Matter and Standard Model Interactions in the SuperCDMS Soudan Experiment  \nAbstract: \nAstronomical observations lead us to believe that dark matter constitutes the majority of the mass of the Universe\, yet it has never been directly observed experimentally. The Super Cryogenic Dark Matter Search Experiment (SuperCDMS) aims to discover the particle nature of dark matter\, by developing and using some of the most sensitive detectors ever built. Previous analyses with SuperCDMS set world leading sensitivity limits to dark matter interactions\, but the analysis techniques have not been based on simulations. Now we have developed an efficient simulations infrastructure that will help better understand the detectors\, develop a better background model\, and optimize the next generation dark matter searches. I present the fully-functional simulations infrastructure to produce high quality samples as well as results for the charge system readout simulations\, and comparisons to expectations from data. Whilst improvement is still needed\, I will show that our simulations well-reproduce dominant features of data\, bringing SuperCDMS closer to a robust simulation-based analysis method\, much needed for the upcoming SuperCDMS dark matter searches. \nJoin Zoom Meeting  \nhttps://lbnl.zoom.us/j/95746341336  \n Meeting ID: 957 4634 1336

SUMMARY:VIRTUAL INPA SEMINAR – Bradley Kavanagh (IFCA - Spain)
DESCRIPTION:Speaker: Bradley Kavanagh (IFCA – Spain) \nTitle: Detection Dark Matter around Black Holes with Gravitational Waves \nAbstract: The observation of Gravitational Waves (GWs) has opened up a whole new avenue for constraining and detecting particle Dark Matter (DM). One of the most promising systems to study is the Intermediate Mass Ratio Inspiral (IMRI): a stellar-mass compact object such as a neutron star inspiraling towards an intermediate mass black hole\, thousands of times more massive than the Sun. Sub-hertz GWs emitted during the inspiral should be detectable by future space-based observatories such as LISA. But the presence of DM in the system can have subtle dynamical effects on the inspiral\, altering the waveform and hopefully allowing us to map out the DM distribution. I will discuss ongoing work to study these systems carefully and self-consistently\, in order to determine whether such a signal can be detected and what we can learn about Dark Matter if it is. \nJoin Zoom Meeting\nhttps://lbnl.zoom.us/j/95929756869 \nMeeting ID: 959 2975 6869

SUMMARY:VIRTUAL INPA Seminar - Matthew Szydagis (UALbany)
DESCRIPTION:Speaker: Matthew Szydagis (UALbany) \nTitle: The Road to Discovering Sub-GeV Dark Matter Using Supercooled Liquids \nAbstract:The latest developments in the search for low-mass dark matter with the snowball chamber technology\, essentially a reverse bubble chamber using supercooled water instead of superheating\, will be presented. The latest calibration data sets with neutron and gamma-ray radioactive calibration sources will be discussed\, with implications reviewed on the extremely low energy threshold expected (sub-keV) and background discrimination as a function of thermodynamic conditions. The most recent three-dimensional image analysis will be shown with position reconstruction and multiple scattering. Information gathered from all prototypes will be analyzed together to form a projected sensitivity curve for both spin-independent and spin-dependent (proton) coupling. \nJoin Zoom Meeting \nhttps://lbnl.zoom.us/j/99047273608 \nMeeting ID: 990 4727 3608

SUMMARY:SPECIAL VIRTUAL INPA SEMINAR – Benjamin Schmidt (LBNL)
DESCRIPTION:Speaker: Benjamin Schmidt (LBNL) \nTitle: A new limit from the search for 0νββ of 100Mo from the CUPID-Mo experiment\n \nAbstract: The CUPID-Mo experiment\, currently taking data at the Laboratoire Souterrain de Modane (France)\, is a demonstrator for CUPID\, the next-generation upgrade of the first ton-scale cryogenic 0νββ-search\, CUORE. The experiment is searching for 0νββ decay of 100Mo with an array of 20 enriched ~0.2 kg Li2MoO4 crystals. The detectors are operated deep under the Frejus mountain at a depth of 4800 m.w.e. in a dilution refrigerator at ~20 mK. They are complemented by cryogenic Ge light detectors allowing us to distinguish alpha from beta/gamma events by the detection of both heat and scintillation light signals. With a bolometric performance of ~ 7 keV energy resolution (FWHM) at 2615 keV\, full alpha-to-beta/gamma separation and excellent radio-purity levels\, we operate in the background free regime. For the present analysis\, we consider more than one year of data acquired between March 2019 and April 2020. With 2.17 kg x yr of exposure and a high analysis efficiency of ~ 90%\, we are able to set a new world leading limit for 0νββ decay of 100Mo. In this seminar\, I will present the details of the analysis\, the new limit and I will conclude with an outlook on the end of CUPID-Mo data taking in July 2020 and further upcoming analyses. \nJoin Zoom Meeting \nhttps://lbnl.zoom.us/j/99340201217?pwd=eEJFSW9BN3pscm1FdDZ3cVpUODBoZz09 \nMeeting ID: 993 4020 1217 \nPassword: 211618
